A liquid bladder type shock isolator for shock isolation of cultural relics and showcases

Abstract

The utility model relates to a liquid bladder type shock isolator used for shock isolation of cultural relics and showcases, which can be used for shock isolation of exhibited cultural relics or showcases, and belongs to the field of shock isolation of cultural relics. Liquid bladder type shock isolator, including a top steel plate, a rubber bladder, a bottom steel plate, an oil injection hole, silicone oil injected into the rubber bladder, a groove, and a raised plate; the top steel plate and the bottom steel plate are connected by a rubber bladder; the rubber bladder is filled with silicone oil Silicone oil is poured through the oil injection hole; the top steel plate is provided with a groove; the bottom steel plate is provided with a convex plate; the size of the rubber bladder is consistent with the size of the groove and the convex plate. The present invention can achieve different use requirements by adjusting the shape and size of the upper and lower steel plates, the thickness of the rubber bladder, and the viscosity of the silicone oil. The utility model has the advantages of simple structure, low height, easy realization of standardization, not only horizontal seismic isolation capability but also vertical seismic isolation capability.

Description

[0001] Technical field: [0002] The invention relates to a shock isolator used for seismic isolation of cultural relics and showcases, in particular to a liquid sac-type shock isolator used to reduce the earthquake damage of movable cultural relics. [0003] Background technique: [0004] The protection of movable cultural relics has always been a matter of special concern to the country. In recent years, with the rapid development of society and economy, the State Administration of Cultural Heritage has paid more and more attention to the protection and restoration of movable cultural relics. In 2011, it added special funds for the protection of movable cultural relics for the first time, marking the beginning of the protection of movable cultural relics in my country. A new chapter in work. The most important item in the protection of cultural relics is earthquake protection. The earthquake damage of a large number of cultural relics shows that the phenomenon of collision and dam...
